The Mercedes AMG GT R can be on the verge of setting what we’re assured will be a “very competitive” lap time at the Nürburgring Nordschleife within the next couple of weeks.

On a passenger ride within the range-topping 577bhp sports car, we recorded a lap time of 7min 46sec while being driven by Thomas Jaeger, one of the GT R’s principal development drivers. AMG insiders are today suggesting which a full-speed run will be between 20 along with 25sec quicker than which. If achieved, which could put the GT R close to the 7min 20sec time of the 13.9-mile circuit which the Porsche 911 GT3 RS claimed last year, along with maybe even the 7min 18sec set by the revised 911 Turbo S.

There’s no doubt which the GT R will become the fastest car in Mercedes’ line-up when which goes on sale later which year. Frank Emhardt, the vehicle’s development boss, reckons which we should see a Nordschleife lap time as being a better metric of overall performance than the vehicle’s straight line performance numbers (an impressive claimed 0-62mph time of 3.6sec). “which can be probably the toughest overall test for any performance car,” he said of the Nürburgring.

Emhardt was reluctant to break down exactly where the GT R’s performance advantage over the existing GT S – which has posted a 7min 40sec Nordschleife lap time – comes coming from, arguing which the improvement comes coming from the whole package: “which’s definitely the combination: the aerodynamics, along with especially the active aero, the chassis revisions, the rear-steering along with the weight reduction.” 

The GT R’s rear wheel steering system can be a first for a Mercedes sports car, however works on the same principle as those used by rivals including the Porsche 911 Turbo. The GT R’s rear wheels can be moved by up to 1.5 degrees in each plain, steering within the opposite direction to the front wheel at low speed to improve agility along with moving within the same direction as the steered wheels at higher velocities to make the vehicle feel more stable.

The active aero features a moveable carbonfibre flap within the underbody. At speeds of over 50mph within the most aggressive “Race” dynamic mode, which flap lowers by 40mm, helping to create a Venturi effect which works in conjunction with the sizeable rear wing to deliver peak aero downforce of 155kg at 155mph. 

Although Emhardt refuses to nominate any cars he considers as rivals to the GT R, we can think of a couple of obvious ones. We’ll find out soon whether AMG has managed to win Nordschleife bragging rights over Porsche along with Nissan.
